mSMD200-16V from TECHFUSE, in a 1812. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Non-polarized PPTC terminal pad (tin-plated nickel-copper); device is rated 16 Vdc max, 100 A max fault current, 2.00 A hold and 4.00 A trip at 25°C. |
| 2 | 2 | passive | Second non-polarized PPTC terminal pad (tin-plated nickel-copper); the pad layout is 1.78±0.1 mm by 3.2±0.1 mm per pad, and the device operates from -40°C to +85°C. |
